Fig. 5. Verification of single and double transfections.
A P1.5 wildtype cochlear sensory epithelial explant (in which HCs do not express GFP) co-transfected with eGFP- and dsRed-expression plasmids at 0.5 μg/μl for each plasmid (a, b). Almost all transfected cells (94%) expressed both eGFP and dsRed. The scale bar = 100 μm.
